BAGUA, Peru .— In February, after a legal battle lasting nearly two decades, little-known indigenous communities in Ecuador's Amazon region won a multi-billion dollar landmark ruling against the oil giant Chevron. The company was accused of polluting a large part of the Amazon basin by dumping billions of litres of chemical-laden materials, which campaigners said destroyed crops, killed livestock and increased cancer rates among the local population.

The oil firm is appealing the ruling, so the indigenous population and other residents affected by the years of environmental damage may never see a cent from Chevron for the clean-up of their lands. Yet, whatever the outcome, it is rare for indigenous people in Latin America to be awarded compensation for damage to their ancestral lands. From northern Mexico to the southern tip of Chile, it's more usual for commercial interests to get their own way when it comes to development projects affecting indigenous people or their territories.

In Brazil, for instance, the construction of the Belo Monte dam, which will flood a huge area, is going ahead even though it will force the displacement of indigenous Amazon tribes, threatening their very survival. In Guatemala, gold extraction at the Marlin mine continues despite an international ruling calling for the suspension of mining operations, and regardless of the fact that the resulting pollution is detrimental to the health of the surrounding indigenous Maya communities.
